DOS_DRIVE

Syntax DOS_DRIVE drive%, directory$
Location SMSQ/E for QPC

This changes the directory the DOS device is connected to.

By default, DOS1_ corresponds to C:\, DOS2_ to D:\ and so on, but the base can be freely chosen in the configuration dialogue or even at runtime:

DOS_DRIVE 2, "C:\WINDOWS"

will assign DOS2_ to the windows directory on the host’s C:\ drive.

PRINT DOS_DRIVE$(2)

would now return “C:\WINDOWS”.
